I'm not saying copy like for like however you can add colour options so that we can create similar looks.
1.The first picture we would need access to changing the beret cap and introduce a jacket with a telnyashka underneath in multiple colour's including black
2.The second picture we already have the tank helmet, balaclava, black gloves. We also have trousers tucked into long boots all you'd need to add is a brown desert camo and you're there.
3.Wood stock on an AK and brown magazines are generic for AK not metal gear.
